Can't you store the energy?
Is the 100 watts max based off of the available kits for sale?
The idea behind it is to not have the resistance in the pedaling action because you are using the magnet/coil setup which will be balanced and easy to spin. I imagine sitting on my deck in a comfortable reclined position for a long time enjoying the view and making power. I guess it is important to know what needs to be powered, which will consist of a laptop, stereo, LED lighting and perhaps a couple larger bulbs, and not to much else.
